Wheel drive and slewing drive solutions
Boosting mobile planetary gear unit performance
Mobile planetary gear models must provide reliable efficiency under extremely harsh circumstances. In wheel drives, this means weighty radial loads, shock loads and tilting motions – all in a limited readily available space. In slewing equipment, coping with the weighty radial loads transmitted to the slewing gear is the challenge.
Advanced bearing plans from Ever-Power can handle these conditions and more. Solutions include:
Wheel drives – Ever-Power gives thin-section tapered roller bearings, thin section angular get in touch with ball bearings, CARB toroidal roller bearings and off-highway hub units (flanged and geared).
Slewing drives – Designed for the productivity pinion in slewing drives, Ever-Power presents Explorer tapered roller bearings, spherical roller bearings and cylindrical roller bearings.
Whatever your drive type and operating challenges, Ever-Power will help you meet them. Working with Ever-Vitality, you can accommodate increased external load, elevated torque and smaller sized and lighter arrangements.the worm planetary gearbox is of horizontally input shaft and vertical output shaft type wall-attached gearbox comprising of three-stage reductions viz. 1 st level of worm gear match and 2 nd, 3 rd stage is designed with planetary
Ever-Vitality industrial, yaw and pitch and mobile phone slew drives are made to work seamlessly in applications requiring slew bearings or perhaps racks, perhaps in a large-capacity winch.
Ever-Electrical power slewing drives are an essential component in keeping fat and size to a minimum on products such as tower cranes, aerial platforms, discharge booms, excavation and development equipment.
Their planetary structure allows them to withstand high torque values while maintaining reduced dimensions, decreased weight and high efficiency. The Dana Ever-Ability slewing drives are suitable for the most serious duties in every environment. The look of the planetary units optimises torque overall performance and radial load capacity, so that you can give excellent meshing between pinion and ring gear.
For accurate adjustment, some versions have eccentric installation between the pinion axis and the casing axis. Their wide variety of ratios enables selecting engine size and type which ideal suits the customer’s.
This wide range of Ever-Power planetary gear units is specifically made for pinion and slewing ring drives. Effectively utilized on tower cranes, shipboard and harbor cranes, wind generators and as steering travel on ship propulsion systems, they works extremely well in all applications where correct positioning is necesary. These Ever-Vitality slewing drives are suited to the most serious duties in every environment. The design of the planetary models optimizes torque overall performance and radial load capacity, so that you can give perfect meshing between pinion and band gear. For accurate adjustment, some variants have eccentric mounting between the pinion axis and the casing axis. Their wide variety of ratios enables the selection of engine size and type which best accommodates the customer’s requirements and program.

Description
Slewing gear drives are used to position driven devices. They have been tried and tested in many different applications, such as for example cranes, excavators, and drilling platforms. Ever-Power gear products for slewing gear drives have a modular design. They are often combined with a long or short lantern equipment drive on the output side. The mounted end result pinions are manufactured based on the customer’s specs. On the input side, you can expect solutions for both electric motors and high-quickness or low-velocity hydraulic motors, a few of which already are standardized.
One frequently requested solution, particularly as a gear unit for slewing gear drives in bucket wheel excavators, includes a Ever-Power planetary equipment product with a bevel or bevel helical gear unit on the input side. The drive electric motor and a brake happen to be arranged on a bracket on the apparatus unit, so that the machine no longer should be aligned on internet site. A brake can be always mounted between your motor and the apparatus unit as a way to repair the boom in a defined position. An overload protection mechanism can on top of that be provided to protect the boom and the drive against inadmissibly substantial loads.

Slew Drives, commonly known as a Slewing Gear or Slew Bearings, is a complete, prepared to install system that consists of a ball or roller slewing band bearing, drive teach, and completely enclosed housing. It can be custom-made with hydraulic or electric motors, brakes, planetary gearboxes, corrosion protection, in addition to many other options.
Ever-Power reduce costs by replacing sophisticated in-house systems in equipment that rotate weighty loads and require efficiency and innovation. Each has an unlimited slewing position and range, move effortlessly and jolt-free, no slip-stick impact, and provide the most effective transmission of high power and torque practical. Our Slew Drives are completely enclosed and sealed housing withstands harsh environments and increases safety.
As a ready-for-installation system module, they replace many individual parts. Slew drives are utilized for aerial platforms, defense technology, public transportation, forestry machine sectors, solar trackers, and more.

Customizable drive solutions, all from one source
Our durable, powerful and flexible industrial gear unit solutions meet your requirements in every respect – the energy rating plus the installation. We provide all the important parts of a slewing equipment drive under one roof:
Motor and motor scoop
Brake between the motor and gear device with torque limiter to prevent excessive loads
Protective covers
Primary gear unit (helical or bevel-helical)
Planetary gear product with pinion shaft and expanded housing at the output
Output pinion
Slewing equipment drives for any power score and mounting position
For larger equipment, the slewing equipment drive can be comprised of various equipment units that effect on the same girth gear with external or internal teeth. We present the right combo of gear models for every requirement:
Our P series professional planetary gear devices and the X series commercial bevel gear and bevel-helical gear systems are adequate for smaller torques of up to 500 kNm. A combo of XP series industrial planetary gear models and X series industrial bevel-helical gear units provide larger torques as high as 4,000 kNm.
Slewing equipment drives are generally shaft-mounted designs. This implies that the apparatus unit is mounted on top and the pinion on underneath. However, our drive answer is also offered as a bottom-mounting version or “bottom-up” version – in this case the pinion is positioned at the top. The lubrication, oil growth tank and the seals are adapted to the installation position.
